[Questionnaire for the assessment of the voice self-concept in a neurological practice : Applicability for the identification of patients with high consultation needs]. / Fragebogen zur Erfassung des stimmlichen Selbstkonzepts in einer Nervenarztpraxis : Anwendbarkeit zur Identifikation von Patienten mit hohem Beratungsbedarf.

ABSTRACT

INTRODUCTION: Hoarseness occurs as a symptom of a multitude of neurological diseases. The importance people attribute to their voice differs greatly and it seems advisable to take this into account during consultation. The Questionnaire for the assessment of the voice self-concept (FESS) is able to measure this importance. The aim of this study was to determine the applicability of the FESS in a neurological and psychiatric medical practice. MATERIAL AND METHODS: A total of 556 patients of a neurological and psychiatic medical practice completed the FESS and the severity of hoarseness was measured objectively by means of the Acoustic Voice Quality Index (AVQI). Another 75 patients only completed the questionnaire. The value distribution of the questionnaire, the correlation with age and gender, the voice quality as well as the daily strain on the voice were investigated. RESULTS: The value distribution ranges of all three scales of the FESS are completely utilized. Floor and ceiling effects do not play a relevant role. Gender and age do not seem to be of significance. The influence of the measurable voice quality is minor. In contrast a correlation between voice self-concept and the daily voice strain was detected. DISCUSSION: The FESS has the potential to be an interesting instrument for the measurement of the subjective importance of a patient's voice. Here reference values are generated, against which individual results can be correlated. The AVQI provides an inexpensive fast instrument for the objective measurement of hoarseness in a neurological and psychiatric medical practice.
